“…0.0016 ppm. Even this maximum concentration is about 30 times smaller than the lowest LC 50 for fishes reported in the literature [30]. In fact, we have observed that the amount of benzoquinone formed during the voltammetric determination of phenol at the Pt/PTy/G electrodes is much lower.…”

A B S T R A C TTreatment of fertilizer production wastewater was investigated by electrooxidation (Eox) process using graphite as the anode electrode and NaCl as the supporting electrolyte. In the studies, graphite anode and titanium cathode electrodes were used in direct oxidation, and together with the addition of NaCl, direct oxidation and indirect oxidation were applied to break the polluters and, therefore, remove total organic carbon (TOC) from fertilizer production wastewater. The effects of operating conditions such as pH, supporting electrolyte (NaCl), current density, and time on the removal efficiency of TOC were investigated. In addition, the specific energy consumption (SEC) for TOC removal performance was calculated. The experimental results showed that at pH 4, 8,000 mg/L NaCl, 360 min. and 62.5 mA/cm 2 applied current density for an initial TOC 950 mg/L, TOC removal, and SEC were found to be 82.1% and 492.3 kWh/kg TOC rem , respectively. According to these results, the supporting electrolyte (NaCl) was found to be very effective for the removal of TOC in the Eox process.

“…As for the ( Figure 8), it shows that in the basic medium the optimal duration of precipitation is relatively much shorter than in acid medium, because of the strong concentration of the electrolyte in ions OH-. The ions Cu 2+ , Pb 2+ , Zn 2+ and Ni 2+ have a big affinity of reaction with the OHions to form metallic hydroxides which are generally very stable [20][21] .…”

The objective of this work concerns the optimization of the operating conditions for the removal of heavy metals from synthetic solution by Electrocoagulation (EC). To reach this purpose, we prepared a synthetic wastewater containing certain heavy metals (Ni, Cu, Zn, Fe and Pb) to study the influence of various parameters (conductivity, pH, time of electrolysis, current density and the initial concentration of the metal) on the rate of removal of these metals. The results show that this rate of removal can reach 99.9 % in the following optimal conditions: pH included between 6 and 8 and a density of the current of 1~1.5A / dm 2 . This study shows that it is possible to remove metals in aqueous solution by the technique of electrocoagulation.
